PPT-Geometry 1.5 Segment and Angle Bisectors

Bisecting a Segment The midpoint of a segment is the point that divides or bisects the segment into two congruent segments A segment bisector is a segment ray line or plane that intersects a segment . Chapter 9. Molecular Shapes. Section 9.1. Lewis structures only provide a 2-D representation of a molecule. However, by including the bond angles of molecules, a more accurate 3-D representation can be achieved. Double Angle. Triangles inside Circles. Angles connected by a . chord. Tangents to a circle.
